How to Replace Dishwasher Capacitor ? Motor capacitor failure can be a common problem with dishwashers. As the machine ages, the capacitor may fail, gradually failing causing slow operation while rotating or stopping, or it may short-circuit causing a loud buzz and no rotation. Remove the top of the machine by removing these screws and sliding back and remove the right side panel to access the motor and capacitor. Locate the capacitor and transfer the wires from the old capacitor before removing it from its socket and reconnecting the new one, then reinstall the panels and try the machine again.

How to Replace Dishwasher Capacitor ? Motor capacitor failure can be a common problem with dishwashers. As the machine ages, the capacitor may fail, gradually failing causing slow operation while rotating or stopping, or it may short-circuit causing a loud buzz and no rotation. Remove the top of the machine by removing these screws and sliding back and remove the right side panel to access the motor and capacitor. Locate the capacitor and transfer the wires from the old capacitor before removing it from its socket and reconnecting the new one, then reinstall the panels and try the machine again., this is a fairly common situation when the machine heats the water and works, but it washes all the dishes very poorly. When starting, there is a feeling that the pump is not working, although it buzzes very loudly, so the device cannot physically wash away food residues. To fix this, you need to get to the capacitor and test it.
First of all, it is worth removing the side panels of the PMM from both sides so that you have access to all the necessary details that can be checked just in case. This is how you can also visually check the integrity of the heating element, as well as measure its resistance in Ohms, in order to know for sure that the problem is in the capacitor.
Now you need to unscrew the pump mounting bolt located at the very bottom of the dishwasher. Usually the pump is held on by only one bolt, so after unscrewing the part will be released. Next, you need to remove the bottom cover of the dishwasher, and carefully disconnect the terminals of the sensor that is installed on the cover in order to monitor the water level.
After that, you can visually inspect the pump, and disconnect the capacitor for testing. If you are not confident in your abilities, take a picture of the connection of the capacitor to the pump, so that later you will not make a mistake during the reassembly of the dishwasher.
The part is disabled, you can carry out tests, and then proceed to the replacement, if necessary. As you can see, you can do it yourself, without the involvement of a master.
Checking and replacing a part
If the PMM heating element is in order, then the problem is in the pump, which can hum strongly during the operation of the heating element, but will not start. And if the pump motor has already been checked, and it rotates freely, but does not turn on, then the problem can only be in the capacitor.
Most often, the capacitance of the capacitor is 5 microfarads. To check its condition, the part must be connected to a transistor tester, for which a regular Mtester V2.07 semiconductor tester is perfect. If the device shows a value much less than 5,000 nanofarads, then the capacitor has lost its charge during active operation, so it must be urgently replaced.
You buy a new part, preferably an original one, so that it fits your dishwasher model. Cheap capacitors will work too, but they can cause installation problems as they usually don’t have a bolt to mount to the pump. Therefore, you will first have to make a fixing bolt to such a device with your own hands, and then attach it using glue, which can be very unreliable and short-lived.
When the capacitor is purchased and ready for installation, it is necessary to carry out all the manipulations according to our instructions in reverse order, assemble the machine and arrange a test wash. If, after taking in water, the pump began to turn on without a loud buzz, and all the dishes after the work cycle became crystal clear again, then the repair was successful. Always keep a close eye on all extraneous sounds that your “home assistant” makes, because this may be the first signal that something is wrong with the device.
